Design longer 25 GbE links without giving up port density. The Finisar FTLF1436P3BCL is a long-wavelength SFP+ optical transceiver built for single-mode fiber deployments where reach matters and rack space does not. With an LC duplex connector and 25 Gbps transport, it fits cleanly into enterprise uplinks, aggregation paths, and interconnects that need dependable optical performance. This module is a strong fit when short-reach optics are not enough and larger form factors add unnecessary complexity. Its long-wavelength design supports structured fiber plant planning, helping teams keep switch ports available while extending connectivity between network rooms, data center rows, and adjacent infrastructure zones. That makes it useful in environments where cable discipline, link stability, and predictable optics selection all matter. For architects, the advantage is straightforward: a compact transceiver class, single-mode reach, and a connector standard that integrates easily into established fiber infrastructure. For procurement, it is a targeted choice that supports the right level of performance without paying for capabilities the network does not need.
